Tips for choosing a contractor in Saint-Jacques
- For larger jobs, insist on a written contract that sets out the price, the schedule and the payment terms.
- Avoid paying a large deposit before work starts, especially in cash.
- Ask for at least two or three written quotes and compare the description of the work, not just the price.
